Wow, I can lift it with one finger - and the rollers don't come out of the track either!
Mike, the garage door guy, was impressed with what cat pee can do to a heavy steel garage door. Now, with all of the cats "out of the way" this new door will stand a chance of survival. Mike had the old one out and the new one installed in a couple of hours.
Then it was my turn.

I read the novel --er, instruction book and spread out the parts for the wonderful new opener. Mom and I worked together to get the motor and chain drive up before she left for the F. H. library. Then I ran the wires and put the garage back together. It all works! Push the button - door goes up - push the button - door goes down.

It is raining like crazy tonight but you will notice that we got the wide panel model. Tomorrow I am installing new wiring for the motor and several 4 ft. garage lights.
What a great gift - Thank you to all of you!
